Cable box connections


The model listed has only ONE HD input and it is on the rear and marked DTV--it is a component input with red, green, blue and a red and white for audio---cable box would have to have same outputs on its rear.

Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.

If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.

A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)

I hope this helps.

I have a D52W20. I bought a HDMI cord thinking it was what I need, what is it that I DO need for HD?


To correctly get HD, you need to satisfy three things.

First you need an HD tv.

Second you need an HD signal. IE.. HD cable box, Blu Ray etc..

Last, you need either HDMI wires or Components wires.


Hook the HD box up to the TV with component wires(I believe you tv doesn't have hdmi connections), go to the correct input and enjoy.

How do I get the HD on this model? Which cables/hook up should I use? I do not have a cable box or set top box but if these are required, please let me know. Thanks!


Your unit is HDTV ready but is not an HDTV. It is capable of displaying HDTV only through the component inputs. Your tuner is analog NTSC and will not receive HDTV or digital.

You could get an HDTV picture using a Blue Ray DVD and hooking up the component connectors from the DVD to the TV.

The only other way would be to get an HDTV tuner with a component output and hook it up the same way, component out to component in, and hook the tuner input to an off air antenna (receiving HDTV) or cable or satellite with HD signals.

Thanks for using FixYa and for the great rating.

How do I connect to Sharp HDTV and Comcast cable


Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps

Turn off closed caption on input(component) on Sharp Aquos 42"


Had this happen on a Comcast box (Motorola DCT 6416 III)
Here's how to fix it:
Turn the cable box off, leave fully connected. Press Menu on the remote
The cable box internal menu will display (Not the Comcast one the Motorola one-- i.e. Display ratios-16:9 etc It's in black and white)
Use the arrows to cursor to the Closed Captioning and toggle to "Disabled" Press Manu again to exit and Voila!

Power the box on an have at it
